Municipality swimming pool in Kalsdorf
(Austria)
Exceptional pool water measurements 
The Kalsdorf pool near Graz is an adventure pool. Like many others, the pool operators want to give their guests only the very best quality, which explains why the local community, and mayor Helmuth Adam, decided to install a Grander water revitalization system. ‘The motivation was to provide our guests with the very best. This also included the idea of using Grander Technology, which had been praised so much in the press.’
Pool manager Fritz Edelmann has kept a record of important data for the pool. ‘The pH should be in the range between 6.9 and 7.6 – ours is at a constant 7.3. The redox potential (ORP), which provides information on the water quality, is at 784; the standard is between 578 and 900. We never had values like this before and they have only become possible with Grander Technology.’
Chemical additives have also been reduced. ‘Even when we have to do a lot of backwashing of the filters caused by the stress on the water of large number of swimmers, the water still remains clear and fresh much longer,’ the pool manager explains. The swimming pools and also the showers, the whirlpools, the diving pool and the drinking water for the restaurant are all using revitalised water, to the benefit of the customers. |
